Prof. Hermann Ney to Speak at IbPRIA 2022 in Aveiro, Portugal

April 29, 2022

The tenth edition of the Iberian Conference on Pattern Recognition and Image Analysis, IbPRIA 2022, will be held in Aveiro (Portugal), May 4-6, 2022. IbPRIA is a single track conference consisting of high quality, previously unpublished papers, presented either orally or as a poster, intended to act as a forum for research groups, engineers and practitioners, to present recent results, algorithmic improvements and promising future directions in pattern recognition and image analysis.

Prof Hermann Ney

AppTek's Prof. Hermann Ney will present "Speech recognition and machine translation: From Bayes decision theory to machine learning and deep neural networks" on Tuesday May 3rd.


The last 40 years have seen a dramatic progress in machine learning and statistical methods for speech and language processing like speech recognition, handwriting recognition and machine translation. Many of the key statistical concepts had originally been developed for speech recognition. Examples of such key concepts are the Bayes decision rule for minimum error rate and sequence-to-sequence processing using approaches like the alignment mechanism based on hidden Markov models and the attention mechanism based on neural networks.

Recently the accuracy of speech recognition, handwriting recognition machine translation could be improved significantly by the use of artificial neural networks and specific architectures, such as deep feedforward multi-layer perceptrons and recurrent neural networks, attention and transformer architectures. We will discuss these approaches in detail and how they form part of the probabilistic approach.
